Non-incision nasal tip cartilage ligation

I had non-incision rhinoplasty 2 years ago. There was almost no swelling and I was able to go about my daily life right away. It was so natural that others wouldn't notice, and although the effect wasn't that dynamic, it was very satisfying in my eyes~ I'm still satisfied. The only thing that bothers me is that the tip of my nose is a little hard... I'm worried that the thread that was tied will rot or something... I hope that won't happenㅠ?;;; Is there anyone who has had a rhinoplasty surgery for a long time ?
